    Gerasim using the wrong GPU

    I have a system with a GTX 660ti and NVIDIA Quadro 600. In the cc_config.xml I have told the BoincClient to ignore the Quadro 600 and it does for all projects except Gerasim. How can I get Gerasim to not use that gpu?

    Re: Gerasim using the wrong GPU

    I have the same problem trying to get it to ignore a 5970. Exclude in place, but continues to use it anyway.

    Re: Gerasim using the wrong GPU

    Did another test.

    System A

    This is the info from a system with 2 Nvidia GPUs. The GPU ID numbers work as expected

    17-May-2016 11:46:11 [---] CUDA: NVIDIA GPU 0: GeForce GTX 780 (driver version 344.11, CUDA version 6.5, compute capability 3.5, 3072MB, 2734MB available, 4336 GFLOPS peak)

    These are the 2 WUs

    System B

    This is the info from the problem system with 2 Nvidia GPUs. The GPU ID numbers reported by the Boinc Client are not the same as the ID numbers used by the drivers. Did not expect that. I excluded GPU 0 and it runs on the 660ti.
